SPECIFICATION forming part of Letters'Patent No. 539,859, dated May 28, 1895. Application tiled August 31, 1894. Serial No. 521,805. (No model.)

To all whom, it may concern:

Beit known that I, JULES JOHN JOSEPH DE RYCKE, a citizenof the United States, residing in Brooklyn, county of Kings, andV State of New York, have invented a certain new and useful Improvement in Separators. of which the following is a specification.

My improvement relates to separators placed within steam boilers for the purpose of furnishing steam from which the entrained water and moisture has been eliminated, and

relates particularly to an attachment to said separator whereby the discharge of the separated water is controlled from the exterior of the boiler. It is especiallyvadapted for usel in the boilers of. railway locomotives.

It consists of a separator mounted in the throttle pipe of the boiler and connections as a rod leading through the boiler shell for operating a suitable drainage valve.

I prefer to use aconnection from the throttle operating mechanism so that the drainage the upper portion of the same, partly in elevalve will open as the throttlevalve opens and close as the throttle valve closes.

The accompanying drawings form a part of this specification and represent what I consider the best means of carrying out the invention.

Figure l is an end View of a boiler. Fig. 2 is a central vertical longitudinal section of vation. Fig. 3 is a corresponding vertical transverse section. The remaining iigures are on a larger scale. Fig. 4 is a vertical section of a portion corresponding to Fig. 2. Fig. 5" 1s a front View of a portion similar to Fig. 3,

partly in vertical section; and Fig. 6 is a vertical section of a portion on apstill larger scale.

I have shown the invention applied to alocomotive boiler of the usual kind.

:A is the shell of the boiler; A', the steam dome; B, the dry pipe, which leads to the exysecured a separator.

terior of the boiler; C, the throttle pipe, and

D the throttle valve.

C is an annular pocketsurrounding a vertical extension of the dry pipe and C2 a passage leading therefrom.

In the upper portion of the throttle pipe is I prefer to use the form shown in a patent to me, dated December 24, 1889, No. 417,774, consisting of a conical body E having helical wings E' adapted to throw the water carried over by the steam, Outward against the surface ot' the pipe and downward into a suitable pocket.

The cone of the separator is supported by a rod E2 extending through the top of the throttle pipe and secured by nutsES.V H-A conical collar e on the rod tits into a corresponding recess in the throttle pipe and insures 6c 'against leakage at this point. It isprevented from turning bythe lug c cast in the interior of the throttle 4pipe and engaged by one of the wings.

The throttle valve D is mounted on the rod D and performs its usual functions.

F is the throttle bell crank turning on a pin c set in lugs C3 extending from the exterior of the pipe C. Theflower arm F of this'bell crank is connected in the ordinary manner to 7o the throttle stem G extending out through a stuffing boX A2 and connecting to the throttle lever Gv controlled by the adjustable stop G2. The upper arm F2 is longer than usual and carries at its end two links I-I I-I curved as shown to clear the throttle stem G. They are connected to a suitable eye on the top of a sliding drainage valve I to be described. The rod D is connected to this arm F2 at the usual distance from the pin c and opens and closes 8o the throttle valve D as the throttle stem G is moved outward .and inward.

The passage C2 leading from the annular pocket C is controlled by the drainage valve I supported by the links H H, and sliding the way or guide C4 gular. opening extending completely through an enlargement on the drainage pipe C2 allowing the valve I complete freedom of motion to any required extent. The opening z' 9oV in the valve I is in the form of a crescent, the upper edge of which coincides with the lower edge of the passage so that a slight vertical 1 motion will uncover a comparatively large area for the escape of any 'water which may 95 have accumulated in thepocket C.

The outer end or nozzle()5 of the passage C2 is covered by a check valve C6 opening outward to allow water to ow past it when the valve I is raised, so long as the steam press- Ioo in which latter is a rectanures in the boiler and in the throttle pipe are equal, and to close immediately When the pressure in the throttle pipe falls.

C7 is a shield below and projecting beyond the nozzle C5. It is provided with a dam or ledge c2 and a drain pipe O8 extending down nearly to or below the water line. The object is to allow the water to drain away from the nozzle without danger of being picked. up by the current ot' steam rushing upward toward the throttle valve. i

The pipe Cs'is of sufficiently large diameter to allow the steam set free at the Water line within the area inclosed by the pipe to escape unobstructedly through the center while the Water descends in a thin film on the interior of the pipe.

It is important that the valve I is free to continue its upward movement after it is wide open, and also that it continues to sink after it has closed the passage C2. This allows for wear on the valve D, and also allows the valves D and I to be so set relatively to each other that, while both move together, the drainage valve shall open last and close first, insuring that steam shall not escape through the passage C2 and pocket C to the cylinders of the engine.

Modifications may be made in proportions.

Although Ihave described the invention as applied to a boiler of the locomotive type, it will be understood that it may be applied to a boiler of any ordinary construction.

Theapparatus will work with some success without the check valve O6 or the shield C7.

The opening in the valve I may be varied and the valve set to give more or less lap as may be found necessary or expedient.

The drainage valvemay be controlled and operated by a rod similar to but independent of the throttle valve gear if such shall be deemed advisable in any case, but Iconsider the forms and the method shown and described as the best means of carrying out the invention..

I claim as my inventionl. A separator located Within a steam boiler, a drainage pocket in which the water is collected, a passageleading such water from said pocket to the unevaporated water in the boiler a valve controlling said passage, and means i as a rod extending through the boiler shell for operating said controlling valve all combined substantially as herein specified.

2. A separator located within the throttle pipe of a steam boiler between the throttle valve and the dry pipe, a drainage pocket in which the water is collected, a passage returning such water a valve controlling the passage, and means as a rod extending through the boiler shell for operating said valve in combination With each other and with a shield arranged as shown to allow the drainage water sacaste to escape without being exposed to the as! cending current of steam al1 substantially as herein specified.

3. The combination in a steam boiler of a separator mounted in the throttle pipe between the throttle valve and the dry pipe, a passage for the water eliminated bythe separator, a drainage valve controlling suchvpassage, a throttle valve controlling the throttle pipe, and connections from the said throttle valve to the said drainage valve so arranged that the act ot opening the throttle valve shall also open the drainage valve all substantially as herein specified.

In a steam boiler, a separator, a passage for the water eliminated by the separator, a drainage valve controlling suchl passage, a throttle valve controlling the throttle pipe, connections as the throttle bell-crank, the links and throttle valve-rod for imparting motion to both valves, in combination with each other, and with means, as the open way CL through which the drainage valve may slide freely to compensate for wear of the throttle valve, all substantially as herein specified.

6.
